ANB-A420 NB-IoT Datalogger with 2× 4–20mA Inputs
The ANB-A420 is a versatile datalogger with two analogue inputs (4–20mA), designed for recording measurements from a wide variety of sensors and transmitters with a standard industrial 4–20mA output. This makes the logger suitable for numerous monitoring and control applications in HVAC, machine building, process control, and building automation.
The ANB-A420 records current values that correspond to physical quantities such as temperature, pressure, flow, air velocity, CO₂, level, or electrical current. Through the OnlineSensor platform, these signals can be converted into concrete measurement units (e.g. °C, bar, m/s, Aac).
Applications
- Measuring and monitoring parameters such as water pressure, air velocity, flow, or AC current
- Monitoring of ventilation, heating, and cooling systems
- Analysis of energy consumption, control valves, and actuators
- Logging of analogue signals from PLC systems or OEM equipment
- Inspection of sensors in test setups or laboratory environments
Thanks to NB-IoT communication, the ANB-A420 offers nationwide coverage and reliable wireless data transmission. The logger is battery powered and equipped with smart data buffering, ensuring safe storage of measurements even during temporary network interruptions.
Key advantages
- Two analogue inputs (4–20mA) for a wide range of sensors and transmitters
- Fully wireless and battery powered – easy installation without cabling
- NB-IoT connection with nationwide coverage
- Memory for 40,000 measurements with smart buffering to prevent data loss
- Integration with ATAL OnlineSensor for 24/7 insight, analysis, alarms, and reporting
- Widely applicable: HVAC, process monitoring, machine building, and OEM applications
Target group
The ANB-A420 has been developed for HVAC installers, machine builders, OEMs, and technical consultants seeking a low-maintenance and universally applicable solution for recording and monitoring analogue 4–20mA signals. The ANB-A420 datalogger offers maximum flexibility: a single compact unit that bridges different sensors, reliable wireless communication, and continuous data recording – providing optimal insight into every process.
